Abstract
The present disclosure relates to an exhaust purification apparatus and a method of controlling the apparatus. The exhaust purification apparatus includes: an injector for injecting urea solution into an exhaust pipe; a driving unit to provide driving force for adjusting an injection angle of the injector; and a control unit to determine the injection angle of the injector based on values of a spatial velocity, flow rate, pressure and temperature of exhaust gas and to drive the driving unit so as to control the injection angle of the injector. In particular, the injection angle of the injector is adjusted by pivotal movement of the injector.
